c#使用wmi

using System.Management;

             ManagementClass mc = new ManagementClass("Win32_Service");
             ManagementObjectSearcher sr = new ManagementObjectSearcher("SELECT * FROM Win32_Service WHERE State='Running'");
/*"Stopped","Start Pending","Stop Pending","Running","Continue Pending","Pause Pending","Paused","Unknown"/*

            foreach( ManagementObject srv in sr.Get() )
            {
                Console.Write(srv["DisplayName"].ToString()+ "\n");
            } 

添加托管类的方法
using WMI.ROOT.CIMV2; //自动生成

ManagementObjectSearcher sr = new ManagementObjectSearcher("SELECT * FROM Win32_Service WHERE State='Running'");
            Service s = new Service();

            ManagementObjectCollection objs =sr.Get();
            Service.ServiceCollection cols = new Service.ServiceCollection(objs);
            foreach (Service ss in cols)
            {
                Console.Write(ss.Caption.ToString() + "\n");
            }
